So is Rafa going to get a zero point penalty and/or fine for withdrawing from Basel and not traveling there for the promotional activities requirement?
According to the rulebook (Section VIII D.):
"Players shall not have the ranking penalty assessed if they complete the requirements for “promotional activities”; are out of competition for 30 days; or the withdrawal complied with the requirements for an on-site withdrawal. Players may appeal withdrawal penalties to a Tribunal who will determine whether the penalties are affirmed or set aside."So, he could theoretically avoid that penalty by also withdrawing from Paris and WTF and submitting a note from the doctor, i.e. per the OOC 30 day+ consecutive rule? Though I doubt he would miss the WTF just to avoid the penalty.
Another loophole is the vague "withdrawal complied with the requirements of an on-site withdrawal", whatever that means.
Finally, he can appeal for discretionary review before a tribunal, which is again pretty vague and I don't think it is transparent, though I could be wrong. Is there somewhere where these decisions are publicly published? I don't know. It seems that we only know the end result once the rankings have been published for a period of time.
So theoretically, he could submit a doctors note to the tribunal that said he needed complete rest, no travel, no activity for a week or 10 days, and the tribunal could affirm it or set it aside.
I'm going to guess he will not get fined, but may get the 0 point penalty...
But anyway, this process is a thorn in the side of automated rankings...

Manual adjustment seems a necessary evil.
